The said bottom 7 isof a height as to extend to approximately half the height of said rearwall 6 and near the proximity to the rear:

. down said inclined surface it will be attacked by the flame `from theburner and wall 6, has a bathe 19.

The inclined inner face of the rear wall.- 6 has a lining of tile asindicated at 20 and` which extends from the upper portion of saidinclined inner face to the lower-end thereof. The inclined face of thebottom 7,

` as indicated at 2l opposes but is spaced from the lower portion of thetile lining 20, under such conditions .providing a discharge runwaywhich is divided by inclined partitons-23 into 'a series of dischargechannels 24.

The side 'walls 12, 13, areI of a thickness less than the thickness ofthe uprights of ,thle base l, but said side walls' are flushed with theouterltace'of said uprights and by setting up the side walls, withrespect to lthe uprights, in a manner as stated, supporting ledges 25are provided upon which is mounted a rectangular frame 26, constitutinga directing element and into which the lower ends of the dischargechannels 24 open. frame 26 are beveled as at 27.

The front uprights oteach pair of uprights have lateral extendingsupporting members 28 which are anchored therein and extend therefromand mounted upon said members 2S in 'the directing element is a coolercomprising acasing consisting-o4l a body portion 29, having a funnel-shad bottom 3() which communicates with a discharge pipe 31, provided withacut-olf 32. Arranged within the body portion 29 are cooling pipes 33,to which a cooling medium is supplied and discharged in any suitablemanner yand the `said cooler element is adapted to receive thedisintegrated bone from the combustion chamber 11', through the mediumoi the discharge channels 24 and directing element and when thedisintegrated bone is supplied to the cooling element it is cooled, andwhen desired discharge Jfrom the cooling element can he had through thepipe 31.

The baille 19, upon the` bottom 7, is in the form of a checker work, asclearly illustrated in Fig. 2, and arranged in advance of thesaid'baille 19 is the inner end of an air supply pipe 34. The latter isbuilt in the bottom 7 and the inlet end of the said supply pipe ispositioned just in advance of a burner which is arranged within thepocket l0 whereby the necessary amount of air can be supplied t6 createthe proper combustion.-

. tile 39.

The inner faces of the ends of the nieces? The top 5 of' the burnerstructure has its lower face set upy in the form of an arch as indicatedat 35 and the said top 5 in proximity to its rear end is formed with atransversely extending inlet opening 36 through which the bone to bedisintegrated is supplied by gravity to the combustion chamber 11, andupon the inclined face of the rear wall 6 whereby as the bone shifts ithereof with va heating chamber 37 of triangular contour andwhichcommunicates with the inlet 36.v The bottom of the chamber 37 isinclined as at 38 and has a face of Secured to the tiles-39 arevertically disposed spaced triangular bars 40 which divide the chamber37 into a series of channels 4l. The partitions 40 as well as theinclined surface of the bottom are of less height than the height of thechamber 37 and extending across the top of the partitions 40 is ahorizontally disposed aper tured member 42.

Arranged forward of the chamber 37 is a dust flue 43, which has its topprovided with a baille 44 and-which has its top opening into the chamber37.forward with respect to the member 42. The dust flue 43 is near thesame height as the chamber 3"( and the lower portion of said flue 43opens into a pair of forward projecting and inward inclined fines 44,45, which open into the lower end of a vertically disposed dust flue 46of materially less width and breadth than the width and breadth ot theflue 43. Opening into the lower end of the flue 4G, as well as into thebottom of the flue 43, is a horizontally disposed flue 47 which isdisposed centrally with respect to the liuc 43. The

flue is of greater height than the flue 43.. `The lower end of the flue46 has an e11- trance opening 48, normally closed by a door 49 and eachof the fines 44, 4G, has an entrance opening 50 normally closed by adoor 51. The openings 48 and 50 and doors 49 and 51, provide meanswhereby access can be had to the lines 44, 45 and 46 t'or the purpose ofcleaning them and the openings 48 and door 49 also permit access beinghad to the Hue 47. i'hrangcd within the rombined flue, hopper andheating chamber structure, at the upper portion thereof' and above thechamber .37, and lines l-l, A14 and 45, is a hopper chan'zber 52, havingits bottom Vprovided with a face of tiling 53. The bottom of the hopperchamber ii'fclines from the front and rear toward the @enter and isformed with an outlet 55.

niemeer chamber is a material supply controlling,Iv clement 60 form/edof an inner and an outer elongated cylindrical member` 56, 57respectively. The outer member 56 is formed with rpairs ot slots V58 andthe slots of each pair of rows are arranged ,opposite each other. Theinner member 57 is formed throughout with rows of slots 59 arrangeddiametrically opposite each other. The slots 58, 59 are rectangularincontour and the slots 58 are adapted to register with the slots 59whereby the material can be supplied. from the hopper, through theapertured member 42, into the heatingr chamber 37. |The open-- ings inthe member 52 register with the channels 4l.

@ne end ci. each of the members G, 5?, is closed as indicated at 60, G1,and extending through the openings 62 formed in the end 60 is a turningbar G3, which is fixedly secured in the boss G4 integral with the end6l. and the member 57. The bar 63 is jour naled in one side of thecombined flue, hopper and heating chamber structure and -projectsoutwardly from said side and provided with a hand lWheel 65. i

The controlling-g element is of a length substantially equal to thewidth of the combined lue, hopper and heating chamber structure and theouter member 56 of said element is liXedly secured within said struc#ture so that it cannot be shifted. The inner member 57 turns Within theouter member 56, through the medium of a bar 63 and a 66, closed by adoor 67' and by suchv an arrangement access can be had to the heatingchamber 37.

The combined flue, hopper and heat-ing chamber structure has the topthereof Aformed with a verticallyl disposed dust flue 68 which has itslower end opening into the v'forward portion of the hopper chamber 52,and furthermore communicates with. the upper portion ot the dust flue 46by an inclined flue 69, the top Wall '70 of which extends' across theupper end of the liue 46.

rllhe top of the iiue 70 constitutes a baille deflecting the dust intothe hopper chamber 52 and in such connection it will be'stated that whenthe draft becomes very great in the retort chamber ll, the bone dust orcertain portion thereof, is carried up Ythrough the heating chamber 3.7,into the flue 43, 'thence through the lues 44, 45, and 4:7 .`into theiue 4G, whero the dust is carried upward and strikes against the battle70 and is then.v

tial

deflected into the hopper chamber 53, by this arrangement Waste 1sreduced to a minimum.

The inclined bottom Wall et the chamber chamber. The battle i9, which isformed of C checker work, will also assist in spreading the flame sothat the material will be fairly attacked Within the combustionchamber.` y

.From the foregoinp' it isfobvious that We have described structurewhereby during the movement *of material 'from the heating chamber tothe combustion chamber it will be continuously subjected to the actionoli heat disintegrating the material and after the saine has beendisintegrated it can be cooled-due to the fact lthat the material isdischarged trom the combustion chamber into the cooler.
